Rosewood bronze cutlery from Thailand, Vintage

Service for 8 with serving pieces, Rosewood handles and what I believe is bronze. This set was purchased in Thailand around 1960. I can't find any hallmarks on them. The set is in like new condition, I don't believe it has ever been used, it belonged to my mother and she never wanted to use it since it had to be hand washed. The fitted case is showing signs of wear, but the service is perfect. Set consists of 3 piece place setting, Knife Fork and Spoon, 2 serving spoons, carving set and sugar spoon.
